2012 JKU Rubi Check Engine Light - Misfire Cylinder 6

A check engine light illuminated on my 2012 Rubi JKU (10,800 miles) this past Sunday. The code indicated "misfire cylinder 6". Took it to Maxwell Jeep in Austin Monday morning and got a call Monday afternoon saying it was ready to be picked up. The service rep said they flashed the computer with a program update and that the problem was solved.

I picked it up this morning and drove it for about 20 miles before the check engine light illuminated once again. Took it back to the dealer and received a call this afternoon saying that they were going to have to go into the engine to find the problem and should know something by tomorrow afternoon.

Has anyone else had a similar problem?

I know a lot of the 12's are having cylinder head problems causing a misfire code, not sure which cylinder number it is. There is a huge thread on here on it.
